Title: The manufacture of oxy and sulpho oxy derivatives of anthraquinone
IPC: C07C50/34
Filed: 1920-12-30
Abstract: 1-oxyanthraquinone-4-sulphonic acid is obtained by heating phthalic anhydride and phenol or phenol-p-sulphonic acid in sulphuric acid containing boric acid at about 200 DEG  C.; further heating of the 1-oxyanthraquinone-4-sulphonic acid, after isolation or not, in sulphuric acid at 240 DEG -250 DEG  C. gives quinizarin; the production of quinizarin from phthalic anhydride and phenol may be effected in one operation; catalysts such as mercury oxide may be added.  If phenol-2 : 4-disulphonic acid is employed or formed, 1-oxyanthraquinone-2 : 4-disulphonic acid and purpurin are obtained. If phenol is replaced by cresols, the corresponding products are 1-oxy-2-methylanthraquinone-4-sulphonic acid or 1-oxy-3-methylanthraquinone-4-sulphonic acid in the case of o- or m-cresol respectively, the final product in such case being 2-methylquinizarin; p-cresol gives directly 1-oxy-4-methylanthraquinone.

Abstract: 1313388 Wire coating apparatus INTERNATIONAL BUSINESS MACHINES CORP 30 July 1970 [22 Aug 1969] 36886/70 Headings G3R R68 R8W R4 and R30X A plurality of parallel wires 10 are arranged in a flat, coplanar formation and passed through extrusion head 21 of extrusion press 22 where they are coated with a melt of a suitable plastics material. The emerging cable 34 is cooled in a first cooling zone 35, where the coolant is air, and then passed, with the plastics still unset, into second cooling zone 38. In this zone, where the plastics sets, the coolant is water, the temperature of which is controlled by heater 44. The cable then passes through an optional third cooling zone 38, where the coolant is water straight from the mains and then through the width measuring device 49 before being wound up. The width measuring device is linked by lines 56 to the heater 44 so that variations in the width of the cable produce, via a conventional control (not shown) signals which may actuate the heater 44. Consequently the temperature of the cooling zone 38 is governed by the width of the cable. Since it is found that, the higher the temperature of the cooling zone 38 is, the greater is the width of the set cable, a predetermined cable width may be maintained by increasing the temperature of zone 38 when the cable is too narrow and decreasing it when it is too wide. The preferred plastics coating material is polyethylene.

Title: Converter for self-clocking digital signals
IPC: H04L7/033
Filed: 1967-08-16
Abstract: 1,144,389. Digital data storage. RADIO CORPORATION OF AMERICA. 16 Aug., 1967 [30 Aug., 1966], No. 37709/67. Heading G4C. A self-clocking input signal having a transition at the middle of a bit cell representing a "1" and a transition between bit cells representing two successive "0"s is decoded utilizing a timing wave derived from the input signal, the phase of the timing wave being corrected if the decoding means indicates two successive "0"s in the absence of an intervening transition. Ideally, the input signal at 16 (from magnetic tape or drum 10) is gated G6, G7 to a flip-flop F1 during the first half of each bit cell for comparison in gates G8-G11 with the input signal in the second half of the bit cell to produce an NRZ output from flip-flop F2. Each transition in the input 16 produces a pulse from unit 17 to synchronize an oscillator 20 producing a pulse train at 22 with twice the bit frequency which is frequency-halved using triggerable flip-flop TF and gate G3 (gate G2 being normally enabled) to control the gates G6-G11 through delays D2, D3. If the NRZ output incorrectly indicates two successive "0"s not separated by a pulse from unit 17 (due to the pulses from gate G3 being in the wrong halves of the bit cells), the pulse (at 40) representing the first "0" will reset a flip-flop F3 to enable a gate G12 to pass the pulse representing the second "0" via an inverter 12 to remove one of the pulses at 22 in gate G2. If there had been a transition between the two "0"s, the flip-flop F3 would have been set again before the second "0" arrived by unit 17. Thus the pulses from gate G3 are arranged to be in the correct halves of the bit cells. This phase-correction if necessary will occur whenever "101" occurs in the message or as a preamble. The NRZ output may be shifted into a shift register by the clock pulses at 301.
